An
Air Force Captain and an Army Captain were sitting next to each other
on an airplane. The Air Force Captain leans
over to the Army Captain and asks if he wants to play a fun game. The
Army Captain just wants to sleep, so he politely
declines, turns away and tries to sleep.

The
Air Force Captain persists and explains that it is a really easy game.
He says, "I ask a question and if you don't kow the answer, you pay
me $5. Then you ask me a question, and if I don't know the answer, I'll
pay you $5."

Again,
the Army Captain politely declines and tried to sleep.

The Air Force Captain, now somewhat agitated, says, "Okay,
if you don't know the answer, you pay me $5, and if I
don't know the answer, I pay you $50!"

Now, that got the Army Captain's attention, so he agrees to the
game.

The
Air Force Captain asks the first question. "What's the distance from
the earth to the moon?" The Army Captain doesn't say a word, but
reaches for his wallet instead and hands the Air Force Captain $5.

Now it is the Army Captain's turn. He asks the Air Force Captain,
"What goes up a hill with three legs and comes down
on four?"

The
Air Force Captain looks at him with a puzzled expression, takes out his
notebook computer, looks
through all his references, and after about half an hour, wakes the Army
Captain and hands the Army Captain $50.
The Army Captain politely takes the $50, turns away and tries to return
to sleep.

The Airforce Captain, a little miffed, asks, "Well, what's
the answer to the question?"

Without
a word, the Army Captain reaches into his wallet, hands $5 to the Air
Force Captain, turns away and returns to sleep.
